I can understand the tiring of everything, since it happens to me occasionally. What I try to do is to find something outside my normal routine to do. Try to find something new to experience, for example:
-find a new TV show to watch
-go to Youtube and look up songs from a genre you never thought you'd like, or never heard of
-Try connecting more with your minor friends, if you can
-Go hang out in a library for a bit if there's one close enough; it's quiet and people likely won't bother you, unless they've met you elsewhere.
-Take up a new hobby, like writing or crafting. You could make some furry ears, or buy some beads and make a bracelet or necklace.
Or, if you want to try a more permenant solution, try talking to your friends and parents about how you feel about all this. Approach them when they're not busy, ask them if they have some time to talk, and tell them you want to have a serious conversation. Try to talk calmly, even if you're irritated, and try to phrase things less like accusations and more like, "When you do (whatever it is they're doing), I feel... (however you feel about it)".
Even if nothing changes, at least you've said something, and communication is the most valuable thing in any relationships. I know it sounds like a lot of self-help malarky, but I speak from experience, and, usually, it helps.
